Application led March 30, 1922. Serial No. 548,201.v l

To all lwhom, t may cof/wem:

Be it known that we,'JoHN G. CoLLIsoN, WALTER N. FRANK, and HARRY M. FI; BERT, citizens of the United States, residing at l Dayton, in the county of Montgomery `and State of Ohio, have invented certain new Aand useful Improvements in Printing Machines, of which the following is a specification, reference being had therein to the accompanying drawing. 1

Our invention -relatesto a printing machine and in particular to a machine for and method of off-set printing.V

This application is filed in place ofthe joint application, Ser. No. 521,673` tiled December 12, 1921; by -John G. Collison and `Walter N. Frank, two of the inventors in the resent case.

T e particular adaptation shown in thi application is that of printing dials forcountei's, gauges and the like, but it will be understood that our invention is adaptable to a `variety of other ap lications.

It is our objectto provide a machine which 4 25 twill print from a flat bed of type or an elec-Y trotype or other similar means. It is our object Vto lrovide a machine for the transmission o the printedimpression through the medium of a yielding surface so as to secure the effects of spo-called olf-setprinting and to insure the transfer to surfaces'of Lhe desired impressions which could vnot be .ordinarilyl secured by direct printing. the t'pe or metal upon the particular sur:

-face esired, such as an enamel or metal surl faceA or a highly poroussurface. It is 'our object to provide a-method an .machine of the' character described for the transmission of just a sucient amount of '40" ink to the surface to bel printed'in the de-4 sired Aconfigurations .so that .not 'only ordi? surfaces but highly delicate and porous,

sur aces can be properly printed with the -;suilicient ,amount of printing ink -or other material used' without blurring orrunning.4

impression and aligmnent of the-im ressions y It isa further'- objectJto provide a 'machine which will be easily-inked, which will be susceptible of the greatest accuracy offor .gauge dials and the like and w 'ch will permit of the ready renewal ofthe type i matter and the use ofcheap flat electrotypes or other plates.

It is a further object of our invention to I v provide for the ready mounting of the material to be printed and the demountingof 1t to insure rapidit vof operation. It is an additional object o the invention to provide such a construction that the greatest accuracy possible will be insured by the elimination of lost movement so that each dupli.- ca te registration will be exactly like every other of the Same terial. u

In the particular adaptation shown here we have ilustrated a machine for printin kind upon the same ma- It is a furtherobjeot to provi ea machine which may be readily re-inked, the ty e matter readily removed, the matter to printed may vbe readily lputin printed position or removed therefrom and Ain 4which the amount of inking may be'suitably controlled.

Referring to the drawings: -Fig. lis a side elevation of our machine; Fig.- 2 Vis an end elevation ofour machine;

an upstandihg rib or wall 2. This wall, supports a bearin as preferred by 'any suitable power such as an-electric motor. The movement vof the handle 5 and conse uently of the shaft d: is

Fig. l3 is a plan view of `al modified inking 3 for .the main actuatingl shaft 4 which is actuated by a lhandle 5 orA limited las the han leis reciprocated back i.

and forth'by lthe stop-pins 6. Upon the wall 2 is mounted a bed 7 fastened theretoby bolts 8. Upon the bed 7 is mounted a type support or carrier :10. This type support is embraced between the plates 11 and 12 bolted S to-7 b' the bolts 9. :Carrier 10 is ada ted to sli e between 'andbeneath these tes a'base of the machine upon which is mounted upon the bed 7 vThis reciprocatory*muove-` ment ofthe type carrier 10 which carrles' the type 13 is secured through a rack 14 retained by a screw 15 upon the side of the :type carrier 10. This rack is in engagement with a master gear 16 which is mounted upon the shaft 4 that is actuated by the handle 5. Also mounted on the shaft 4 is a transfer wheel' or drum 19, which may be of any suiti this shaft 28b 'is xed a gear 17 which bears able material, such as rubber or one of the compositions in the art. This drum is of such diameten and so positioned as to engage the'type 13 carried by the support 10 as the latter reciprocates on `the bed t..

' Formed Aon the base 1 is .a bearing l through which passes a shaft-1b, one end of the shaft projecting in front of the bracket 2 and` carrying an arm 28 provided at'its upper end with a bearing 28a through which passes a shaft 28b secured .againstlongitudinal movement in one direction inthe nearing by means of a washer 28 and nut 28. On

against the other end of the bearing 28Fi and prevents movementof the shaft in the opposite direction.' This gear 1-7 meshes withv the I.' gear 16 so that as the latte-r is rotated' by the crank handle, theshaft 28b will be rotated. On the innenfendof the shaft 28b there is also provided ahead 18 adapted to fit within the drum-or cy1inder.18a which is to receive on its periphery the article to be printed bythe roller 19. A tension spring v27 has to have theimpression transferred froml that -roller-to thesurfaceof such articles, the cam one end attached to thearm 28 andA its other end attachedto an opening27a fixed in the bracket 2.. This vtension spring.` is so posi tioned as toconstantly urge the arm. 28 andthe head 18 in the direction ofthe transfer rollerv19. Projecting `from the arm 28 is a bracket 286' carrying a roller 28t .which is held by the actionV of the spring I27 to bear against a cam 36 Fixed on` the shaft 4;- This cam is so shaped-and positioned that the artic-les to be printed lwillbe brought against.

the transfer roller 19 only at the proper time being arranged to hold the arm '28 away from the transfer roller 19 at other times.

' .On the shaft 1b is also mounted a. bracket ,1"A through which passes a bolt 1d on which l is mounted an arm 1 provided at its upper end with a handle 32 which'projects from theside of a bearinfr 33 supporting a shaft I 33 having at one end a. head 34- adapted to bear' an'ainstthe fia-t endof thefdrum or- .cylinderjlS to be printed whenthe latter is on the mandrel or support 18. This arm 1e .is secured at one. end to a pin 3() projecting is normally urged in the 4direction of said mandrel by means of a 'coil spring 29 which from the bearinnl. and at its other end to a .pin 31 vprojecting from the arm 1. By this means the cylinders or drums to be printed r willbe securelv held on their mandrel -while .21", the springs being tension springs.

rotating freely with such mandrel when the gears 16 and 17 are in mesh and the shaft 28b is rotated. l

In the Operation of the device provision -is'made for inking the type and to this end arm 21 is an ink distributing roller 20 w against which the roller 23 is held by means of springs 24, each having one end fixed to a pin 25 carried by a respective arm 21, andv its other end fixed to a 4respective bearing A pin 21d' serves tolimit the downward movement of the roller 2O and holds it in posiltion to4 engage the type as they pass underneath said roller: l'In using the device the crank 5 is s o positioned as to move the arm 28 away from the shaft 4. The handle 32 is then grasped and the .arm 21e swung back- -wardso that the article to be printed may be slid ont-he mandrel 18.4- The handle 32 is i then released, whereupon the head 34 clamps the article securely on the mandrel. handle 5 is then `given a completefoscill'ation The in one direction being'that shown by the the impression of the typ'e ismade on the transfer roller 19 and from .there -is con-l veyed to the article 18 on the drum 18, this taking place by reason of the cam'36 having been rotated at the .proper time by the action of the movement. of the crank. to permit the cam roller 28t to ride on the low-'part of the' cam` and consequently to permit the' article on the drum 18 to Ibear against thel transfer roller. 'The' crank` handle 5 is then rotated inthe opposite direction until it comes in' 'contact with the other stop pin 6. At .this

time the high vpart of the cam will force the arm 28 away. from the shaft'4'and by Yarrow in Figure 1.- This'moves the type on- -its bed under the type inking' roller 20 and proper manipulation let the handle 32 the arm 1 is swungback and the printed 'article removed from its mandrel, an unprinted varticle being placed inl position forfthe next operation.

Inorder to insure thorough distribution of the ink in cases where a broaderface of type is to -beused than asingle'line' for mak.

mg up legends for dial faces, we employ the' mechanism shown in Figures 8 and 4 which takes the place of the inking roller andthe attendant mechanism '.shown'; at the right hand of Figure 1.

In these figuresr there is villustrated a inotor 46 which drives a lworm A45 meshing with the worm -wheel 44 carried on ash'aft 44- supported in brackets 44". On this shaftis also an ink'distributing roller 40 and. a gear 43. rl`his gear 43 meshes with ra gear 42 fixed l on a shaft 42,a carrying a second distributing roller 39. The gear 42 also meshes with a gear 41 fixed on a shaft 41 carryinga third ink distributing roller 38 which bears a ainst the fourth distributing -roller 37 xtending between the brackets '44 is a shaft 47 supporting a pair of arms 48 carrying a shaft 49 whereon is mounted the type llinking roller 50. O n the side ofthe type support is mounted a cam 51which engages a roller 52, carried by one 0f the arms 48 when the type carrier or support is moved in one direction so that the type inking rolleil 50 is lifted at this time in to contact with the fourth distributing roller 37 and receives ink therefrom. As the typ'e carrier 10 moves in the opposite' direction the roller 52' passes off of the cam 51 and the type inking roller 50 drops on the type and inks the same.

Thus by means ofthe series of ink distributing rollers a more even supply of -ink is obtained.
